Abstract
Description
Technical Field

[0002] As a core piece of equipment in the knitting industry, the circular knitting machine's cylinder head is a key moving component. It plays a crucial role in supporting and driving the cylinder of the knitting needles in circular motion. During operation, the cylinder head initially rotates at a set speed. As production demands change, the speed gradually increases. As the speed increases, the high-speed rotating cylinder head generates a strong centrifugal force, which uses the machine oil instead of the machine oil for rotation. In some cases, the machine oil may even be thrown out of the oil pan, resulting in oil waste and requiring frequent oil replenishment. Utility Model Content

[0035] An anti-oil-spraying structure for a syringe base includes a disc base 1, on which a large disc gear 2 is rotatably mounted. The disc base 1 has an oil groove 11, which is annularly arranged on the disc base 1. The large disc gear 2 has a protrusion 21 annularly arranged on the disc base 1. When the large disc gear 2 is mounted on the disc base 1, part of the protrusion 21 is located inside the oil groove 11. The annular oil groove 11 can store lubricating oil, providing a lubrication basis for the rotation of the large disc gear 2. The protrusion 21 extends into the oil groove 11, and during rotation, it can carry oil to the friction surface. The oil wiping area is protected by the annular structure of the oil groove 11, which restricts the oil from spreading outward. The disc seat 1 is also provided with an oil-blocking protrusion 12. The large disc gear 2 is provided with a recess 22 corresponding to the position of the oil-blocking protrusion 12. The oil-blocking protrusion 12 also has an extension 121, which is located inside the recess 22. The cooperation between the oil-blocking protrusion 12 and the recess 22 forms a physical barrier. After the extension 121 is embedded in the recess 22, the possibility of oil overflowing through the gap is reduced, thus achieving a preliminary anti-oil spillage effect.
[0036] When the large disc gear 2 is installed on the disc base 1, a gap is formed between the protrusion 21 and the oil-blocking protrusion 12. The oil-blocking protrusion 12 and the extension 121 have a first oil-blocking wall 122 and a second oil-blocking wall 123 on the side facing the protrusion 21. The gap design allows the large disc gear 2 to rotate freely, avoiding additional friction caused by rigid contact. At the same time, the first oil-blocking wall 122 and the second oil-blocking wall 123 form a double barrier. When the engine oil overflows to the outside as the large disc gear 2 rotates, it is first blocked by the first oil-blocking wall 122. A small amount of engine oil that crosses the first oil-blocking wall 122 will be intercepted again by the second oil-blocking wall 123, reducing the probability of oil leakage.
[0037] An oil guide groove 124 is also provided on the side of the oil baffle protrusion 12 facing the large disc gear 2. The oil guide groove 124 is a semi-circular groove. Several guide grooves 124 are provided and distributed at intervals along the circumference of the large disc gear. The oil guide groove 124 is located between the first oil baffle wall 122 and the second oil baffle wall 123. When the oil breaks through the first oil baffle wall 122 and the second oil baffle wall 123 to be blocked, the oil guide groove 124 can collect part of the oil and return it to the oil tank 11. At the same time, it can prevent the oil from accumulating at the corner formed between the oil baffle protrusion 12 and the extension 121.
[0038] The oil baffle protrusion 12 is also provided with an oil return groove 125, which can collect the residual oil after the oil baffle wall blocks it.
[0039] Based on the above structure, by pouring engine oil into the oil sump 11 and mounting the large disc gear 2 on the disc base 1, when the large disc gear 2 rotates and causes some engine oil to splash, the oil-blocking protrusion 12 can initially block the oil. Subsequently, as the rotation speed gradually increases and the height of the oil splash increases, the extension 121 can provide secondary blocking for the oil, keeping the oil between the oil-blocking protrusion 12 and the extension 121. Furthermore, the oil guide groove 124 can guide the oil blocked by the extension 121. The oil is guided to flow back into the oil tank 11 along the oil guide groove 124. At the same time, the oil-blocking protrusion 12 also has an oil return groove 125, which is located on the side of the extension 121 away from the oil tank 11. It can collect the oil that passes through the extension 121. Through the cooperation of the oil-blocking protrusion 12 and the extension 121, the oil can be blocked twice, thereby solving the problem of oil splashing and wasting oil when the large disc gear 2 rotates.
[0040] In one embodiment, reference is made to Figures 1-3 The large disc gear 2 has a protruding extension 23. When the large disc gear 2 is installed on the disc base 1, the protruding extension 23 is located in the oil return groove 125. During the operation of the syringe base, the large disc gear 2 generates centrifugal force when it rotates, causing the oil to pass over the first oil barrier 122 and the second oil barrier 123. The protruding extension 23 forms a physical barrier in the oil return groove 125, which can effectively prevent the splashed oil from spreading to the outside. At the same time, the gap between the protruding extension 23 and the inner wall of the oil return groove 125 is small, which further restricts the splash path of the oil. When a small amount of oil is splashed out and comes into contact with the protruding extension 23, it will flow into the oil return groove 125 along the protruding extension 23 under the action of gravity and structural guidance, thus avoiding oil pollution of the external environment or other parts, thereby achieving the purpose of preventing oil splashing, ensuring the cleanliness of the working environment of the syringe base, and reducing the maintenance costs and equipment failure risks caused by oil leakage.
[0041] In one embodiment, reference is made to Figure 1 and Figure 2 The disc base 1 is provided with a return channel 13. One end of the return channel 13 is connected to the oil tank 11 and the other end is connected to the oil return tank 125. The return channel 13 forms a circulation path between the oil tank 11 and the oil return tank 125. When the oil collected in the oil return tank 125 reaches a certain amount, it flows into the return channel 13 through the overflow tank 131 and then returns to the oil tank 11, realizing the recycling of oil.
[0042] The oil return groove 125 is provided with several overflow grooves 131 that are spaced apart along the circumference of the disc base 1. One set of overflow grooves 131 is connected to the return channel 13. Adjacent overflow grooves 131 are provided with through grooves and are interconnected. The through grooves between adjacent overflow grooves 131 enable the oil in the oil return groove 125 to be evenly distributed, avoiding overflow due to excessive local oil accumulation, and further enhancing the anti-oil spillage effect. This design not only prevents oil waste, but also maintains the oil balance of the oil system, ensuring that all components of the syringe base can be continuously and well lubricated, and extending the service life of the equipment.
[0043] In one embodiment, reference is made to Figure 1 and Figure 2 The base 1 is provided with a liquid inlet channel 14. One end of the liquid inlet channel 14 extends to the outside of the base 1 and the other end extends into the oil tank 11. The liquid inlet channel 14 provides a convenient way to replenish the oil tank 11 with oil. During the operation of the equipment, the oil will gradually decrease due to consumption, evaporation and other reasons. Through the liquid inlet channel 14, the operator can easily add oil to the oil tank 11 without disassembling too many parts, which improves the convenience and efficiency of maintenance. In addition, the liquid inlet channel 14 is directly connected to the oil tank 11, which ensures that the newly added oil can quickly integrate into the system and quickly participate in the lubrication work, maintain the normal operation of the equipment, and avoid component wear and equipment failure due to lack of oil.
[0044] In one embodiment, reference is made to Figure 2 The return channel 13 is also equipped with a drain trough 132, one end of which extends to the outside of the base 1. A plug 3 is movably installed on the drain trough 132. The plug 3 can be a flexible rubber plug or an internal hex screw. The drain trough 132 provides a discharge port for the oil in the return channel 13. When the equipment is maintained, repaired, or the oil needs to be changed, the plug 3 is opened, and the old oil in the return channel 13 and the oil tank 11 connected to it can be discharged through the drain trough 132. It can also be used to clean and repair the inlet channel 14. This design facilitates the oil change operation, can more thoroughly drain the old oil, and avoid the mixing of new and old oil affecting the lubrication effect. At the same time, the movable installation of the plug 3 can effectively seal the drain trough 132 during normal operation, prevent oil leakage, and ensure the sealing of the return channel 13 and the normal operation of the oil circulation system.
[0045] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4The oil sump 11 is provided with inclined ends 111, and two sets of inclined ends 111 are symmetrically distributed. The two sets of inclined ends 111 make the oil sump 11 have a conical cross section. The conical cross section of the oil sump 11, with the guiding effect of the inclined ends 111, allows the oil to naturally converge to the bottom of the oil sump 11. During the operation of the equipment, even if the oil is unevenly distributed in the sump due to vibration or other reasons, the inclined ends 111 can still guide the oil back to the bottom, ensuring that the oil pump and other components can stably draw oil and maintain the normal operation of the lubrication system. At the same time, this structure helps to settle impurities in the oil. Impurities are more likely to settle to the bottom of the cone under the action of gravity, which facilitates later cleaning, improves the cleanliness of the oil, and thus improves the lubrication effect and service life of the equipment.
[0046] In one embodiment, reference is made to Figure 1 and Figure 2 A maintenance port 15 is also provided on one side of the plate base 1. The maintenance port 15 is connected to the return channel 13. A plug 3 is movably installed on the maintenance port 15. The plug 3 can be a rubber plug with extensibility or an internal hex screw. The maintenance port 15 is connected to the return channel 13 and can be used to clean the channel when blockage occurs. The presence of the plug 3 ensures the sealing of the maintenance port 15 when no operation is required, preventing oil leakage and external impurities from entering the return channel 13, and ensuring the stable operation of the oil circulation system.
[0047] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The base 1 is also surrounded by a waste oil tank 16, and a return oil tank 125 is located between the waste oil tank 16 and the oil tank 11. The waste oil tank 16 is designed to provide a containment space for oil that may leak or cannot be properly recovered. When the return oil tank 125 overflows due to special circumstances, the overflowing oil will first flow into the waste oil tank 16, without directly polluting the external environment or other critical components. The return oil tank 125 is located between the waste oil tank 16 and the oil tank 11, forming a buffer barrier, which further reduces the risk of oil leakage to the outside. At the same time, the oil collected in the waste oil tank 16 can be cleaned regularly, which facilitates the monitoring and maintenance of the oil leakage of the equipment and ensures that the syringe base is always in good working condition.
